Description

The Pavilion, formerly known as Syon Park Boathouse, is a late 18th-century structure with a stucco facade designed by J. Wyatt. It is a single-storey building featuring a 1:3:1 arrangement of windows. The central bow has three semi-circular arched French windows, flanked by four Ionic columns, and is topped with an entablature, parapet, and balustrade. The wings of the building have double-hung sash windows set in sunk panels. Their entablature and parapet, which contain a stepped panel, are lower than the central features and do not visually connect with them. The Pavilion is topped with a domed green roof. Notably, the original boathouses and grilles have been removed, and a granite sett terrace along with a sloping bank now runs in front of the Pavilion.

Local climate

Syon Park Boathouse the Pavilion sits in one of the driest parts of the UK, with an average of 700 mm of rain a year. This makes it drier than 92% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 90% of listed buildings.

It experiences an average of 30 freeze-thaw cycles a year, fewer than 64% of listed buildings. Of these, 13 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
